A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an essential oil field environment. The application load was very large and would have to be transported vertically over an extended distance.
The client also asked to reduce the weight of the structure while keeping a high level of safety.
Because of the high loading, ATLANTA offered a multi-drive remedy, which gear rack for Woodworking Industry shared the load over four pinions operating on two lengths of rack. This allowed a smaller sized rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy had not been important for the application, an induction-hardened rack was used. This rack acquired induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter long racks were utilized to maximize the number of mounting screws utilized per section and dowel pins had been utilized to pin the racks in place.
The Ever-Power solution met all the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning machine has pairs of base plates, each plate having a recess to received a slicing insert. Each pair of foundation plates is mounted on helpful information plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of each pair of base plates engage a common pinion installed on the tubular shaft. The radial distance of each base plate is modified by a screw and the racks and pinion be sure that the radial adjustment could be exactly the same for each person in the same pair of base plates.

Linear motion is indispensable to moving machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural quantity, life, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-generation technology with limited positioning precision. However, this assumption is invalid.
Precision-ground mounting surfaces to restricted tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and small, low-mass styles are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic overall performance and unlimited travel distance. Some include high quality servogears and actuators with backlash less than 1 arc-min., effectiveness to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for security and smooth motion.
